How much blockage in artery or arteries can cause a heart attack. Also does blockage come from plaque and clot.

Blockage is 100% to suffer an injury the artery must get closed off for a period of time. Talks about percent stenosis (narrowing) reflect how much of the native artery remains open for flow, that number also gives an estimate about how possible it would be for a small clot to come along and plug up that vessel. The usual way the "door slams shut" is when a clot floats in and finishes making a blockage.

Could dissolving with effective supplementation "plaque" from inflamed arteries dislodge and cause stroke or heart attack pre-maturely? %?

No. Stating drugs have been shown to decrease plaque. Most OTC supplements have not been proven. If you have plaque cussing symptoms you should talk to your doctor about treatments.

But if there are pits/nooks/crannies (call it what you like) there can still be tumbling blood that can clot and cause stroke. Any symptom should be discussed with your neurologist. Read more...
